KTP-SESH-P (А,SN)

KTP-SESH-P (А,SN)

KTP-SESH is a modular-packaged unit and a part of the integrated power system. Connection to MV line is organized via a medium voltage cubicle KSO-SESH.For transformation of the energy dry(TSZ-SESH) and oil (TMG-SESH) distribution transformers are applied. 
To protect outgoing feeders, LV switchgears are completed with circuit breakers VA-SESH.Complete transformer substations are dedicated to accept, transform and distribute the electric energy with alternating-current, voltage 20,10,6/0.4,0.69 kV.

APPLICATION

  • Nuclear power plant;
  • Thermal and Hydro power stations;
  • Oil pumping stations.
